- /*
- * This header file describes the structures of the file format for "fat"
- * architecture specific file (wrapper design). At the begining of the file
- * there is one fat_header structure followed by a number of fat_arch
- * structures. For each architecture in the file, specified by a pair of
- * cputype and cpusubtype, the fat_header describes the file offset, file
- * size and alignment in the file of the architecture specific member.
- * The padded bytes in the file to place each member on it's specific alignment
- * are defined to be read as zeros and can be left as "holes" if the file system
- * can support them as long as they read as zeros.
- *
- * All structures defined here are always written and read to/from disk
- * in big-endian order.
